Specialized Visualization Tools:

Importance of Data Visualization in EDA:

Components of Visual Encoding:

Boxplots Use & Interpretation:

Heatmap Purpose & Example: Shows data values using colors (e.g., correlation heatmap).

Scatter Plots Use: Shows relationship between two variables; used to detect correlation and trends.

Area Plots, Line Charts, Bar Charts Comparison:

Dendrograms in Hierarchical Clustering: Tree-like chart showing merging of clusters; used to visualize hierarchical grouping.

Bubble Charts Enhancing Scatter Plots: Adds third variable using bubble size; helps show more information in one graph.

Word Clouds in Text Data Analysis: Displays frequent words visually; useful for tweets, reviews, feedback analysis.

Geospatial Visualizations:

Correlation (r): $r = [N\sum XY - (\sum X)(\sum Y)] / \sqrt{[(N\sum X^2 - (\sum X)^2)(N\sum Y^2 - (\sum Y)^2)]}$
Slope (b) of Regression Line: $b = [N\sum XY - (\sum X)(\sum Y)] / [N\su
